A form-shapable tarpaulin material incorporates a malleable component that enables the form-shapable tarpaulin material to be shaped into a formed shape and retain this shape. The malleable component may be coupled to a first side layer which may be a plastic layer that is waterproof. The malleable component may be continuous or discontinuous, such as including strands that form a screen or net. The malleable component may be configured between a first side layer and a second side layer, or sandwiched between these two layers. A form-shapable tarpaulin material may have a drape angle of no more than 25 degrees.

A pipe insulation product including a core of insulating material and a laminate surrounding the core and bonded to the core. The core may include an outer surface; an inner surface; and a wall extending between the outer and inner surfaces. The laminate may include a foil or metallized polymeric film sheet, a scrim, a porous media sheet, and a polymeric film sheet bonded together via an adhesive. The laminate may include a closure flap that is configured to adhesively seal opposite ends of the laminate together to form a cylindrical tube with the core enclosed therein. The closure flap may be configured to include a curl that provides a greater closure flap adhesive seal.

The present invention includes an apparatus for protecting an aerodynamic surface from erosion including a screen capable of being applied to a leading edge of the aerodynamic surface; and an erosion protection coating applied to the screen before or after the screen is applied to the leading edge, wherein the erosion protection coating protects the aerodynamic surface from erosion.

Described are composite grid structures that have a plurality of ply layers, each one of the plurality of ply layers comprising a plurality of first elongate tapes oriented in a first direction and a plurality of second elongate tapes oriented in a second direction, the second direction being offset from the first direction by an angle of at least 25 degrees. In the grid structures: each of the first elongate tapes has a first length extending between opposing ends of each of the plurality of first elongate tapes and a first midpoint intermediate the opposing ends, and each of the second elongate tapes has a second length extending between opposing ends of each of the plurality of second elongate tapes and a second midpoint intermediate the opposing ends. Associated composite laminate structures, grid structures, and methods of manufacturing and/or using the same are also disclosed.

The present application relates to athletic field covers with wind-refracting layer.

Systems, methods, and devices of the various embodiments provide for the creation of holey graphene meshes (HGMs) and composite articles including HGMs. Various embodiments provide solvent-free methods for creating arrays of holes on holey graphene-based articles formed from dry compression (such as films, discs, pellets), thereby resulting in a HGM. In further embodiments, a HGM can used as part of a composite, such as by: 1) embedding a HGM into another matrix material such as carbon, polymer, metals, metal oxides, etc; and/or (2) the HGM serving as a matrix by filling the holes of the HGM or functionalizing the HGM body with another one or more materials. In various embodiments, HGM can also be made as a composite itself by creating holes on dry-compressed articles pre-embedded with one or more other materials.

A composite foam article is disclosed herein. The composite foam article comprises a polyurethane foam core presenting a first surface and a second surface facing opposite the first surface. A first skin is disposed on the first surface and a second skin is disposed on the second surface. The first and second skins comprise a plurality of fibers and a polymeric binder. The composite foam article also comprises at least one supplemental layer comprising an ethylene and acrylic acid copolymer dispersed in and/or disposed between any of said aforementioned skins and core.

Flooring material has an anti-slip, noise reducing pad directly self-adhered to a bottom surface. The pad is formed by applying a foamable PVC material is directly on the bottom surface of the flooring and heating the PVC material to foam the PVC material. The PVC material may then be cooled to form the pad with a definite formed shape having a resilient outer surface layer and a spongy foamy inner structure.

A web harness belt includes multiple layers. A first elastomer layer portion and a second elastomer portion each connected to a ballistic material layer of the multiple layers. The first elastomer layer portion and the second elastomer layer portion each including multiple belt configuration slots.
